Kesan Percambahan dan Rawatan Haba terhadap Gamma Amino Butyric Acid (GABA) dan Asid Amino dalam Beras Perang Cambah Varieti MR 219

Abstract

The aim of this study was to evaluate the gamma amino butyric acid (GABA) and amino acid content in products obtained from MR 219 germinated brown rice. The investigation included MR 219 white rice, MR 219 brown rice, MR 219 germinated brown rice (GBR) with different germination time and heat treatment and commercial germinated brown rice. In this study GABA content in germinated brown rice variety MR 219 (35.59 mg/100 g) was significantly higher (p<0.05) than commercial germinated brown rice (12.60 mg/100 g), MR 219 brown rice (1.43 mg/100 g) and MR 219 white rice (0.82 mg/100 g). Results indicated that heat treatment significantly alter the amount of GABA, serine, glutamic, histidine, threonine, alanine, proline, valine, lysine, isoleusine and leucine. It was found that the essential amino acids; histidine, threonine, tyrosine, valine, lysine, isoleucine, leucine and phenylalanine showed significant increase (P<0.05) in MR 219 germinated brown rice compared to other germinated brown rice samples.
